Hundreds of people lined up at a Manhattan bookstore to meet Hillary Rodham Clinton for four seconds and have the potential 2016 presidential candidate sign a copy of her new book being released Tuesday.

The Barnes & Noble store in Union Square had wristbands to give out to the first 1,000 people in line, who were told they'd get four seconds with Clinton and could not pose for photos with her. She was expected to sign copies of her book, "Hard Choices," for about two hours.

"It's really about the hard choices everybody has to make in life," she told the crowd before sitting down.

Sean Brennan, of Queens, said he stood in line because he wants to tell her to run for president again.

The former Democratic senator from New York says she has not decided whether to run again.

Clinton's book was released Tuesday amid a media blitz of television interviews that touched on a wide range of topics, including the tough 2008 campaign.

The former secretary of state told NBC's Cynthia McFadden for an interview airing Tuesday on Nightly News that her advice for a younger version of herself would be to not take everything so personally.

"I would say that what I have learned and really incorporated since – to take criticism seriously, but not personally, not to be so anxious and worried about everything that everybody says and try to figure out how to incorporate that into your thinking," she said.

Clinton said the White House reviewed the book before it was published but did not ask for any changes.
